How do astronauts eat in space?
Most of their food has to be prepared in a special way to ensure that it can be eaten in weightlessness. The most common preparation for space is dehydration; the astronauts rehydrate it simply by putting it in their mouth or adding water.
How do astronauts take showers in space?
They do not take showers in space. With such limited access to the ISS, the Station has to work as efficiently as possible - and water is one of the most precious onboard resources. Anyway, showers are not convenient in weightlessness - the water just floats around. Instead, astronauts use wet towels.
How do astronauts go to the toilet in space?
The toilet is designed for use by both males and females. A seat belt and foot restraints hold the astronaut on the seat, while high-speed air currents pull the waste into the respective receptacles. The urine is combined with other water waste and the faeces are vacuum-dried, chemically treated to remove odour and bacteria, and stored.
How do astronauts sleep in space?
Astronauts cannot lie 'down' in a bed because of the weightlessness. Sleeping bags are strapped to bunks to keep them from floating around. Astronauts can sleep standing up, upside-down, or even suspended in the air.
What do the astronauts wear in space?
There are no special clothes - the astronauts wear ordinary clothes like T-shirts. There is no washing machine on the ISS, and it is hard to pack enough clothes like underwear or socks, because each kilogram launched into space is very expensive. The result is that they cannot change their clothes every day: underwear is changed every 2-3 days. On average, ISS crewmembers get one pair of shorts and a T-shirt for every 3 days of exercising. Their work shirts and trousers/shorts are changed, on average, once every 10 days. There is usually a new T-shirt to wear under their work shirts every 10 days.
